Pour oats into a mason jar and cover with milk. Add in the rest of the ingredients (except for the cocoa nibs topping which will be added the next day).
Stir to combine all ingredients so they're evenly dispersed and seal the jar with a lid. Store in the refrigerator overnight.
When ready to eat, sprinkle the top of the oat mixture with the cacao nibs (you can also add extra raspberries if desired)
